And in order to make it work, you have to (actively) remove the 71 and 72 versions? signature.asc Description: This is a digitally signed message part.

Package: firmware-iwlwifi Version: 20221109-4 Severity: important File: /lib/firmware/iwlwifi-cc-a0-72.ucode X-Debbugs-Cc: fishyw...@gmail.com Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? * What outcome did you expect instead? *** End of the template - remove these template lines *** With firmware iwlwifi-cc-a0-72.ucode, the wifi chip would throw "Microcode SW error detected" after the system is idle for a while. After wakig up the system, the wifi would appears to be connected (in NetworkManager), but pinging the router will give "Destination Host Unreachable", and I have to turn wifi off and one again in NetworkManager to fix it.
